Javascript 如何用php加粗回声

我只想在我的选择中加入一个营地，但我不知道怎么做

这是我得到的数据

public function get_clientes()
{
    $sql="SELECT concat(firstname,' ',lastname) as fullname,id_user, card_number FROM amcpcgg_user ORDER BY card_number ASC";

    $clientes=\helpers\common::object_to_array($this->_db->select($sql));

    $ret='';

    foreach ($clientes as $cliente)
    {
    $ret .= "{id:'" . $cliente['id_user'] . "',text:'" . $cliente['card_number'] . ' ' . $cliente['fullname'] ."'},";
    }

    if ($ret!="") $ret=trim($ret,",");

    return $ret;
} 

< script type = "text/javascript" >

  $('#cliente').select2({
    allowClear: true,
    multiple: false,
    data: [ <? php echo $data['clientes']; ?> ]
  });

< /script>

这里是我打印数据的地方

public function get_clientes()
{
    $sql="SELECT concat(firstname,' ',lastname) as fullname,id_user, card_number FROM amcpcgg_user ORDER BY card_number ASC";

    $clientes=\helpers\common::object_to_array($this->_db->select($sql));

    $ret='';

    foreach ($clientes as $cliente)
    {
    $ret .= "{id:'" . $cliente['id_user'] . "',text:'" . $cliente['card_number'] . ' ' . $cliente['fullname'] ."'},";
    }

    if ($ret!="") $ret=trim($ret,",");

    return $ret;
} 

< script type = "text/javascript" >

  $('#cliente').select2({
    allowClear: true,
    multiple: false,
    data: [ <? php echo $data['clientes']; ?> ]
  });

< /script>

我想加粗$cliente['card_number']

简单的方法是

echo "<b>". $cliente['card_number']."</b>";

echo”“$客户[“卡号]”；

根据你的情况，你可以做如下事情

$card_number = "<b>".$cliente['card_number']."</b>"; 

$card_number=”“.$cliente['card_number']。”；

并通过

$card\u number

检查一下

你问的不是很清楚。您所说的

bold

卡号是什么意思？你的意思是用粗体显示文本吗？是的，但我不只是打印卡号，而是打印整个查询，但我在这里定义了回音，

“{id:”。$cliente['id\u user']。”，文本：“$cliente['card\u number']。”。$cliente['fullname']。”

我不能只回显卡号，我会试试看，w8秒

$card\u number=“”。$cliente['card\u number']。”；foreach（$clientes as$cliente）{$ret.=“{id:'”“$cliente['id_user']”，text:“$card_number.”.$cliente['fullname'].“}，”；}

我这样做了，但它只是打印了一个错误，您应该创建

$card_number=“”。$cliente['card_number']”内部
foreach
。正如您所看到的，打印
